What is PDF Merging and Why Use It?
PDF merging is the process of combining multiple PDF files into a single PDF document. This feature has a wide range of applications, from business to legal sectors, education to personal use. It's especially a lifesaver when there's a single-file requirement for official applications like UYAP (Turkey), e-Government, and other formal submissions.

Common Issues and Solutions
❌ Getting "File too large" error
Browsers have a 200MB limit. Solution: Compress each file separately, then merge. Alternatively, merge in smaller groups with fewer pages.
🔄 Page order gets mixed up
After uploading files, drag pages from the page preview on the right to arrange them in your desired order. Each page can be individually controlled and organized.
📄 Blank pages appearing
Scanner or printer errors may cause blank pages. In page preview, visually identify blank pages, select them, and delete.
🔐 Can encrypted PDFs be merged?
No, password-protected PDFs cannot be merged. You need to remove the password first using Adobe Reader or another tool. This is a security feature.
